T0 a ZZ w7wm z't mag concern:

Be it known that we, SIMON SOHLANGEN anal IGNATZ NEUMANN, citizens of the United States, residing in Chicago, oounty of Cook, and State of Illinoi's, have jointly invented new and useful1mprovements in Btmg-Stoppers and Bung-Bushes, 0f which the following 1s a specification, reference being had to the accompanying drawings, illustrating the invention, in which Figure l, is a top, or p1an view of my improved bung stopper inserted in the bush and the bush inserted in a barre1. Fig. 2, is an inverted view 0f the bung stopper inserted in the bang bnsh and the bush removed from the barrel; Fig. 3, an inverted view of the rubber ring inserted 0n the hub 0f the bang stopper removed from the bung bush and the ring below the rubber and the cam-plate removed from the hab; Fig. 4, a vertical Sectional elevation of the complete device inserted in a barrel; Fig. 5, an inverted view of the complete bung stopper removed from the bung bush; Fig. 6, an elevation of thehub of the bung Stopper; Fig. 7, a plan of the ring which lies round t'he hub and between the rubber and cam-plate, removed; Fig. 8, an e1evation of the co'mplete device removed from the barre1.

This invention relates to the eonstruction of a bang stopper and bung bush wherebya rubber ring is coxnpressed laterally b6tween a flange on the hub of the bang stopper and a ring which lies between the oam-plate and the rubber fing; and the radial cams bythe turning of the cam-plate are locked in two inelined serpent ine racks each opposing notch of which serves 1:0 lock oho cams so that the bung stopper eannot'be removed unless cousiderable foree is applied to a wreneh fitted into said hub, as the whole will be readily comprehended by reference t0 the following detail description.

A, represents that portion of: a barrel, or cask into whieh the bang bush B, is inserted by means 0f a suitable serew thread 011 its periphery, in the ordinary manner.

The primary portion 01: the bang stopper consists of a central cylindrical portion G, whieh is east so1id with a. eap O which projects over the cylinder G in the form of a fiange; and also east solid with rivet-studs g.

In the middle t 0p portion of the cap is formed a wrench sea.t D by which and a, wreneh the bung stopper is 130 be insorted and removed. A rubber 1ing F, substantially oircular, in cross section, is placed around the cylinder G 130 bear against the under side 0f the flange formed by the outward projecting cap G, as shown at Fig. 4. The seeondary portion wonsists of a, flat ring J whieh is also plaeed around the cylinder G to bear against the under portion 0f the rubber ring. The tl'uird. portion eonsists of a circular plate E whioh is recessed out ab its top portion at K t0 engage the peripheryof tl1e 10 wer end 0f the oylinder G, and it is provided with as many vertical holes through it as there are rivot-studs g projeeting down from the cylinder G, and also with two opposite lugsf and f, which in cross seetion are conirex on their top portions properly 130 enga.ge oho notches 0x depressions in serpentine earns H, H. The plate E is secured 110 the cylinder G by the heading down of-the rivet-studs g.

The bnng bush B is of ordinary construction exeopt the serpentine oams mentioned. It is provided with asorew thread to be turned into a barrel or cask, with an internal flange J a1: its 1ower end, opposite s1ots through Which the lugsf,f, pass, and also With opposite serpentine cams H and H. The difiiculty in the use of plain inclined carns as tightening surfaces for the lugs t0 operate on, is by handling barrels provided with such devices thelugs become quite readily loosenedand the gas from the beer escapes. T0 remedy this difficulty we have found it necessary 130 form depressions in the cams H, with rounded intermediate portions so tha1; the lugs will have, when in place, a firm seat; while at the same time the lugs can be turned back to permit the bung stopper to be removed. Tha.t this may be accomplished the rubber ring E must eontain oonsiderable stock whereby the neoessary contraction and expansion may be attained; arid further it becomes necessary that the said ring has four bearings within its seat, viz:-=one on the under side of the (lange of the cap O, 0ne on the eylindrioal portion G, one 011 the ring J, and one against the inside of the bung-bush all the space for exp'ansion being the differenco between 1she oireulam rubber in eross section und the square of the seat in whieh it lies, in eross section. As the devices comefrom the manufactory; the lugs brough' into the first depression in the cams H, will shut; off the escape 0f any pressure of. gas which the barre1 will withstand; bat after considerable use the 1ugs 02m be.inserted in the seeond depressions. are made from a thorough test 0f rhe devioe. The novelty is fully set*forth in the elaim; therefore any other construotion not eontaining the elements claimed would n0t eontain our invention.

We claim as new and desire to sgcuye by Letters Patent of the United States A bung stopper consisting of a centrafeylindrical portion, an integral cap formingfl flange at Lhe top 0f said smopper, a nubber ring These statements SIMON SOHLANGEN. IGNATZ NEUMANN. WVitn esses:
